[Uisp-dev] Failed to enter programming mode.

[Harald Vogt]

I get this error message when trying to upload a program. I have an AVR ISP
programmer. When I run (on Linux):

$ uisp -v=4 -mode=s -dprog=stk500 -dpart=ATmega128 --upload if=helloworld.hex

I get the output:

Failed to enter programming mode.

I know that it has worked at some point. But I don't remember what I've
changed since then... Does anybody know a fix for this problem?

Thank you
